6.1.2 WEST RAND CLN<br />
This CLN consists of six transmission substations supplying both residential and industrial loads. The load growth in<br />
this CLN is stable; no new large loads are expected. The main projects in the West Rand CLN are as follows:<br />
Establishment and Integration of Demeter 400 kV Substation<br />
• Install new Demeter 400/88kV MTS 2x 315MVA transformers.<br />
• Loopin the Proposed Verwoerdburg – Pluto 400kV 400kV line into Demeter 400kV(30km) 2015<br />
West Rand Reinforcement<br />
• Westgate B 400/132kV substation (1st 500MVA transformer) 2017<br />
• Hera-Westgate B 1st 400kV line 2017<br />
• Taunus-Westgate B 1st 400kV line 2017<br />
• Taunus Ext 400/132kV transformation (1 x 500MVA) 2017<br />
• Etna-Taunus 1st 400kV line (energised @ 400kV) 2017<br />
• Glockner-Hera 1st 400kV line 2017<br />
• Glockner-Enta 1&2 400kV lines operated at 400kV 2017<br />
• 400kV Busbar at Etna S/S 2017<br />
• Construct Etna 2x800MVA 400/275kV 2017<br />
6.1.3 NIGEL CLN<br />
This CLN consists of six substations which are supplied from Lethabo power station (via Brenner), Matla power station<br />
(via Nevis and Benburg) and Kriel (via Zeus-Grootvlei). Grootvlei and Benburg show considerable load increases.<br />
In 2013, load will be moved from Snowdon to Kookfontein, thus reducing the loading on Snowdon.<br />
The main projects in the Nigel CLN are as follows:<br />
Snowdon Transformation Upgrade<br />
• Replace 4x 275/88kV 90MVA with 3x 160MVA transformers 2012<br />
Benburg Transformation Strengthening<br />
• Install a third 275/132kV 250MVA transformer at the Benburg MTS 2016<br />
Nevis Transformation Strengthening<br />
• Install a third 275/132kV 500MVA transformer at the Nevis MTS 2017<br />
Siluma 275/88kV MTS Establishment<br />
• Establish new Siluma MTS 2017<br />
• Loop the Lethabo–Eiger, Snowdon–Brenner into Siluma 2017<br />
• Loop the Brenner–Eiger 275kV line into Siluma 2017<br />
• Install 2x 275/88kV 315MVA transformers 2017<br />
